I wonder if this is the Elemental that spoke to Blackhand when he sacrificed his hand to save his clan.

It really wouldn't surprise me, considering the Iron Horde seems to try and use whatever 'tools' they can get a hold of.

For all you priests out there making full use of their Mind Control, there are a few catches to this.

First off, any mob you used Mind Control on, will receive the Infuriated buff afterwards. This is permanent and not removable. In other words, you can only mind control a mob once and it should be nuked to death shortly after to avoid unnecessary damage.

Since the first phase is more about control instead of a mad dash to get the Heat Regulator's down, mind controlling the Furnace Engineer's is generally a waste of effort. However, it does help to end a phase, so with some training and communication you can "force" the phase transition by using Mind Control on the Furnace Engineer's and manually casting Bomb on designated targets. This'll ensure a phase transition when you want it - in a perfect scenario when you've cleared most of the mobs and before new reinforcements arrive.

When the second phase arrives Mind Control is a good spell to use on the Security Guard. There are two abilities not listed on WoWhead, as well as the permanent passive of Elemental Slayer. The two abilities are a stomp-taunt and a direct damage ability that both only work on Slag Elemental. The perfect strategy is to mind control a security guard when an elemental is at low health. (Mythic difficulty will do this at full health as to remove the buff). Make sure the Slag Elemental is near a Primal Elementalist and then cast the stomp-taunt. Follow up with the Slay Elemental. The guard itself will be hitting for a substitutional amount. Melee should move out of range and let ranged DPS finish the Slag Elemental and let the security guard eat up the Slag Bomb. If this does not finish off the guard he should be nuked down thereafter.

Firecaller's are the final mob that are susceptible to Mind Control. Their noteworthy ability of Cauterize Wounds is useless when used on players. However, it can still cast Lava Burst which has a mana cost. It's possible to drain his mana this way, but it only stops future Lava Burst casts for a short while. The primary use of using Mind Control on the Firecaller is stalling all other instant spellcasts of the Firecaller which are not available to the player.

Too busy running around during the encounter to pay attention to what was said or are just curious to find out, but don't want to go into the raid? No problem, here it is! Enjoy!

Foreman Feldspar yells: Protect the furnace at all costs!Foreman Feldspar yells: I will crush you!Foreman Feldspar yells: Get those billows pumping!

Blackhand yells: The machinery is damaged. Keep those scum from sabotaging the furnace!Blackhand yells: The furnace is overheating! Fools, if the Fury breaks free, our work will be ruined!Foreman Feldspar yells: Call in more security!

Primal Elementalist yells: The Fury has broken free!Primal Elementalist yells: Quick, get it under control!Primal Elementalist yells: Warlord, we have it under control.Foreman Feldspar yells: Turn up the heat boys, we'll sweat 'em out!Primal Elementalist yells: It..is free. Warlord, we have failed...

Heart of the Mountain yells: Freeeedommmmm!Blackhand yells: A small victory, but now you will perish in the flame that burns at the heart of Blackrock!Heart of the Mountain yells: SUFFER!Heart of the Mountain yells: Drown in fire!Heart of the Mountain yells: My flames will lick the flesh from your bones!Heart of the Mountain yells: My fire is..Exting..uished.

The Heart of the Mountain is very much into his job, so he tends to repeat himself during the fight about suffering and drowning in fire - I didn't know fire was now a liquid. =/ This can be a very long fight, depending on your group, so by the time your toon is attempting a fancy tap dance to avoid the fire on the ground, you're about ready to have this thing done and over with. Personally, I find it hilarious that my fire traps as a hunter actually do damage and my elemental shaman is a bit confused on how her fire elemental even hurts this guy. Magic. =D

As long as you fight in the fight while on the legendary ring quest, you will get Elemental Runes. You don't have to actually hit the Heart of the Mountain. So if the tanks don't do their job properly, the healers miss you, or you just stand in fire. As long as you participated you'll still get it.

Comment by Cropz

So, with the new patch and Mind Control not working on the Security Guards at Lv100 anymore, this fight on Mythic seems impossible to do, am I missing something here?

Security Guards were reduced to Level 101, so it's again doable.

This will definitely be solo-able with higher item level than mine. I can get it down to about 20% on my 838 Blood Death Knight before the stacks get too high and I just can't out-heal it.

Comment by tigersaurusrex

Solo'd on normal as an 865 Demon Hunter tank. It was fairly easy if you know the mechanics, but was definitely a dps check in the 3rd phase. I'll overview my strategy for those not familiar with the fight. You can probably use other strats, but this is what worked for me so it should work for you too! (maybe)

Phase 1: I picked a side and sat on the edge of the Heat Regulator (I stayed on the edge so if rupture or a shield dropped I could run to the other edge). I wailed on Feldspar and cleaved down the other adds. When the bomb button popped up I clicked it. I pretty much always had bombs and when I didnt there was usually a nearby bomb bag I could click to grab one. When the first regulator died I just ran to the other side and did the same. This went really fast, each regulator died in like 30 secs. I ignored the bellows operators but if you have low health/survivability you might want to kill a couple as you cross to the other side or something.

Phase 2: I kept waling on Feldspar, popped Meta immediately and cleaved down adds. The damage was big but not too intense, I probably would've survived without Meta. Once Feldspar died I finished off the Bellows Operators, and everything was dead once they were finished. After that it's just a game of killing the Slag Elementals on top of the Primal Elementalists to drop their shield and then kill them. I killed each Primal within half the time you get, so I didnt worry about the other adds and just cleaved them.If you have low cleave/dps you might want to kill the firecallers before killing Primals so they don't get healed (disclaimer: i have really low dps so you'll probably be fine)

Phase 3: This is the sweat phase. I pulled the boss to one side of the room and moved the bare minimum to get out of melt when it dropped. Slowly make your way around the room as you do this. Make sure adds are dead before you wail on the boss (i finished them before the boss was active, and you can ignore any slags that are still up as they dont do much). Make sure to save all CD's for this phase, use DPS ones at the start of the phase and defensives around 50% or for when you start taking too much dmg.

I killed the boss around 20 yards from the far wall, so I was cutting it pretty close. Any lower geared/non tank toons will probably find this much harder and possibly impossible til they're better geared. Overall it was very easy, just a bit nerve-wracking at the end.Similarly geared tanks who know the fight mechanics should find it just as easy. :3

As described by tigersaurusrex this is soloable in normal and heroic. Unitl its changed, mythic still needs the mind control to break the elementals shield.

It is probably far easier for some classes, like Prot Warrior or Demon Hunter, than others.

One thing to note for phase 2 - the Slag Elementals do not fixate and move to melee range. You have to run a tad past the Primal Elementalist to get the elemental to stand on the shaman, so you can dps him and force the shaman's shield to break.

Iron Assembly

Blackhand's Crucible

Blast Furnace

The Blackrock clan’s unique ability to smelt the black ore, a substance so dense that ordinary flame does not even soften it, has always been their most closely-guarded secret. Deep within the Foundry, their furnace contains a primal force as old as Draenor itself, raging within the confines of its prison as it emanates a preternatural heat.
